I have been looking at some i5 motherboards for a friend's new build and I noticed all the Mobo's I find for i5's all have 24+8 ATX pins.
However, the only PSU's I can find are 20+4's. Would it be possible to use a 20+4 for the 24+8 ATX motherboards? If not, can someone spec me a PSU to go with this?.

I think you need to look at the specs more closely. The 20+4pin usually refers to the fact that the PSU is backwards compatible with older motherboards with the 20 pin design, whilst still compatable with new designs (the 4-pin splits off the 20 pin, giving either 20 pins, or 24 pins - which is what you want).

As for the 8 pin, just make sure the PSU has an 'EPS12V 8 pin' connector.

Here's an example: OCZ 700W PSU

Particularly this bit:
- 1 x 20+4Pin ATX
- 1 x 4-pin/8-pin CPU (supports double CPUs/supplies stable voltage)

This means you have the 24 pin motherboard connector (the main one), and the EPS12V 8 pin connector - which is for the CPU power. Ergo, this will work.

Ah, overlooked those specs. I did not realise that 20+4 was just quoting backwards compatibility with older standards. Thanks for the info!

So I assume if the specs say:
1 x 20+4 motherboard connector
1 x 4pin CPU connector

then I can use both +4's to make a +8?
